Patent: Canon RF 70-240mm f/4 IS and RF 70-300mm f/4-5.6 IS

Would the L designation necessarily be included in a patent application?

Not per se. But in the Canon lineup, there is only one constant aperture zoom lens that’s not an L lens, the EF-S 17-55/2.8 IS (unless I’ve missed one or more). All FF constant aperture zoom lenses are L. To me, that suggests an RF 70-240/4 IS will have a red ring.

I agree... I think that for the RF trinity tele you might get your choice of f2.8, or f4 with slightly longer reach. Kind of like 24-70 f2.8 vs 24-105 f4.

I guess it means different things to different people. What’s affordable to us may be very expensive to others.

however, Neuro is right. reading the OP: We also expect some more affordable offerings ....

So not an affordable lens in absolute terms but relatively affordable in comparison to available RF lenses. makes sense.

Well, I’m just speculating based on what he wrote in the description. I’m not saying it’s right, or wrong.

200$ 70-240 f4 would be cool and prolly possible to make. But yeah sounds like red ring stuff.
Or maybe not ,cheapest full frame ef zooms seems to be 500E

Actually this is the newest patent for FF mirrorless 70-200/2.8 (for Example 1, 2and3 ), aspherical UD lens is utilized, extremely high resolution and good multi-wavelength abberation correction.
